first off credit for the model goes here: 
https://www.thingiverse.com/thing:330913 the website has a pretty good 
selection. the ones that i've used have been in stanford triangle 
format. they've also been airtight and fairly dense face count so the 
are great for subsurface and glass. i like this granite version ... 
can't decide if marble / subsurface is next ... or glass!

here's some others i've used:

Nice.

How about, marble with a glass sphere inside>

Or glass filling the voids. Maybe a CSG nightmare but I sure would want to try
that.

I might never get a 3D printer but that's a great idea for a source of models.
Not that I know much of anything about it but I would expect most, if not all,
to be very "solid".

i've also thinking a media version ... shafts of light coming through 
holes might look pretty cool too

that would indeed be a cool toy to have ... maybe i should buy lotto 
ticket. if i win i could call into work rich and perhaps buy one or two!

I must confess I got it from the last image on the link above.

But on reflection, <g> maybe the other way round would take longer. ;)

Marble/subsurface.

Very cool.

I've always wondered how a uv_map(!) could possibly be constructed for the
texture of such a shape. Seems like it would have to be done in another
space/time dimension! :-P

What is the reflection(?) or thingy on the left side of the image? Very curious.

Hmm, after further scientific analysis, it looks like a shoe footprint(?)
